Features

• Build new columns from the ones you already have. Define a column as an expression over existing columns, using add, subtract, multiply, or divide. It then behaves like any other column: profiled with summary statistics and correlations, and ready to use as a feature, target, or filter. Division guards against a zero divisor by returning an empty value, so ratio metrics like claim count over earned exposure are safe to build. A structured editor previews each row as you go.
• Create one geography from many files. Select a whole set of boundary files at once, such as 50 per-state shapefiles, and they're combined into a single geography on upload with no external GIS step first. Uploads run in parallel with combined progress, and single-file uploads work exactly as before.
• Deletions now show up in the activity feed, so a removed dataset, model, or geography leaves a visible trace.

Improvements

• Large, dense maps now render at every zoom level. Geographies with hundreds of thousands of areas, like Texas census blocks, used to come up blank when zoomed out. Areas now merge as you zoom so the map stays readable at any level.
• Distribution chart series are now colored individually, while the bars stay neutral.
• Better keyboard navigation, control labeling, and screen-reader support throughout the app.
• A range of modeling, mapping, and data-processing operations run faster on large datasets.

Fixes

• A Tweedie model's power setting no longer reverts to its default when you reload the model.
• The AI assistant no longer drops characters mid-response when connected to a local model.
• Restored support-chat message delivery.
• Fixed a crash on the model page caused by automatically built features.
• Gamma and Inverse-Gaussian fits now reject non-positive responses instead of failing silently.
